Specification of Letters Patent.

Application filed January 27, 1906. Soria1No.298.258.

Patented EL 7 29, 1906.

To all whom it may concern:

Be it known that l, FRANK P DEER, a citi Zen of the United States, residing at Balti improvements in trucks for railwaycsrsj and the object of the invention is to produce a simple and efficient device of this nature in which a series of tandem Wheels positioned, preferably, underneath the center of the car is employed in place of the usual wheels which are arranged in pairs and requiring two tracks.

My invention consists, more specifically, in the provision of s truck having a plurality of axles journaled therein and provided each with a wheel having a central flange about its tread and adapted to engage a slot interme: diate the rails and in the provision of means carried by the truck for keeping the slot clear of obstructions.

My invention consists, further, in other details of construction and arrangements of parts, which will be hereinafter full de'-- scribed and then'speciiically defined in the appended claim; l 1

the accompanying drawings, in which-- Figure 1 is'a top plan viewof my improved truck. Fig. Zisje'sectional view centrally throughlthe truck; an an edge elevatlon of one of the wheels, shown as resting upon the track with the flange'of thejrailen motion tefalow the truck topass about curves offtracks without unnecessany" friction, and j ournaled injsaid truckers the axles ing a t eadsurfaee which is divided c'entrallv by an integral flange D, projecting from the circumference of the wheel, said flange being preferably of a width equal to the tread-sur face upon either side of the flange.

E E designate the rails, which inner ends angled, asjat E, and are f'astened to the girders or beams H, with their inner angled ends overhanging the inner walls of said beams and spaced apart a! suflicient dis tance to receive the flan e D and allow the same to turn therein wit out much friction. Swiveledtoeach end of the truck are the pilotsK, the lower ends of'which are winged and are adapted to travel in the slots in ad-.

Vance of the wheels for the purpose of clear ing an obstructions which mi ht enter the space etween the beams on portions of said rails.

It will be noted from the foregoing that by the provision of the ilots, which have a swiveled movement a lowing the same to turn about curves, ell obstructions will bekept out of the way of the wheels, which will have wide bearing-surfaces upon the rails, and by reason of the flange extending between the rails the wheels will he held to the rails. Y

It will also be noted thatby the provision have their the angled of the apparatus shown and described a con 5 siderable amount of frictionis. dispensed with by reducing the contact s'urface of the wheels one-half over the ordinar'y'trucks requirine' wheels airanged in pairs upon the ends of the axles.

What I clairn,is-- V in (JOIIlblIlSttiUllfWlllll. the truck-of a car exles mount ed thereon, wheels rotatlngiwith said axles and provided each-with a central flange; tracks-having their inner ends angle'd and extending into a slot ola conduitnnd' adapted to hold said flange ver ticnlly in theslot ofthe; cdnduit, pilots-havingishank portions 'journaled in the endof thejti'uck and having wingedends adaptedto travel in said slot, the upper edge of the; wingedportion being inclined backward and upwardfrom the levelanddescribed.
